a variety of willemite found in New Jersey are known as troostite. In 1866, Dr. Benjamin F. Shumard named a genus of fossil blastoids Troosticrinus in his honor. In 1909, Elvira Wood edited and published Troost's unpublished monograph on the crinoids of Tennessee (1850). This brought Troost's previously unknown work back into geological and paleontological discourse.
